I got it based on the demo, it's not fantastic, but a great time filler.
After a bit of time on it, I started to get used to the table and understood a bit better what I had to do, by about my 5th game I was hooked.
I moved on the the next table, which is an extreme gaming based machine, and found the limited area at the bottom to be frustrating. The small area adds an annoying repetative nature to the game (especially if you are as unskilled as me). Frustration with this table set in and hasn't left me.
The last table is a secret agent themed machine, and I found this one quite enjoyable. It has elements that keep you trying and keep you returning, and is the table I have spent most of my time on to date.
The fact that future downloads are possible has me hoping for more tables down the track, but truthfully only a few XLA games have been blessed with expansions.
